[00:27] <IrcsomeBot1> <Anarcho Taoist> Hi all! I am getting screen glitches occasionally. Particularly with Latte Dock. It looks like TV static. When I scoll over the icons it clears up. What could be the cause? Kubuntu BB on Dell Precision 5520
[01:44] <Delvien> IrcsomeBot1: sounds like compositor problems
[02:26] <IrcsomeBot1> <Anarcho Taoist> @Delvien, Right - where do I start in looking at that?
[08:00] <robk> got a question, so I installed the newest nvidia drivers, and it totally borked my kubuntu 18.04 system
[08:02] <robk> I ran sudo apt-get remove --purge nvidia-* && buntu-drivers autoinstall
[08:02] <robk> basically, I tried to install the nvidia-390 drivers, and everything just went to crap.
[08:02] <robk> system ran beautifuly before.. and now it's a brick. KDE refuses to load.
[08:02] <robk> :(
[08:03] <diogenes_> robk, and did you have nvidia proprietary installed before?
[08:06] <hateball> robk: 390 are terrible with Plasma
[08:06] <hateball> robk: if you want later, use 396.xx from the driver PPA, those work
[08:06] <hateball> robk: https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa
[08:09] <robk> okay, so it's possible that plasma is barfing due to the graphics-driver stuff I added for nvidia-390, so I need to use 396?..
[08:09] <robk> I thought 390 is the newest?
[08:09] <hateball> latest long lived
[08:10] <hateball> doesnt change that it does not work as it should
[08:10] <robk> okay, so my graphics is a quadro M2000M
[08:10] <robk> with prime
[08:10] <robk> so it's both intel + quadro
[08:11] <robk> so I have that repo added, which driver package should I install exactly?
[08:11] <hateball> nvidia-graphics-drivers-396 I think
[08:11] <hateball> I am not on my nvidia machine atm
[08:11] <hateball> "apt search nvidia|grep 396" otherwise :)
[08:12] <robk> says it's already installed
[08:12] <robk> KDE refuses to load, some applications launch, but the main KDE doesn't show anymore :(]
[08:12] <hateball> what driver are you using according to nvidia-settings ?
[08:12] <robk> I had to install xdm just so I could login.
[08:13] <hateball> robk: and you didnt do anything like run X apps with sudo?
[08:13] <hateball> which could break permissions
[08:13] <robk> never.
[08:13] <hateball> hmmm
[08:13] <robk> I downloaded nvidia's .sh driver
[08:13] <robk> turned off x
[08:13] <robk> chmod +x
[08:13] <robk> and ran it w/o the GUI running like I've done in the past
[08:14] <robk> thought since they make the driver for all of this stuff it would just work.
[08:14] <robk> :(
[08:14] <robk> I was trying to fix the vsync issue with my graphics.
[08:14] <robk> intel worked okay, but felt very laggy
[08:14] <robk> i'm on a 4k laptop.
[08:14] <robk>                                 
[08:14] <hateball> so... you've used both nvidias driver as well as PPA?
[08:15] <robk> so my problem is.. I poped back in this kubuntu disk and no reinstall dialog like ubuntu used to have.
[08:15] <hateball> hmmm
[08:15] <robk> okay, so I thought adding the PPA would fix things.
[08:15] <robk> I added the PPA and nothing works now.
[08:15] <robk> I mean apt packages are fine, just video wont' come up, I mean I see a crosshair on the screen, but nothing is showing up.
[08:16] <robk> I got xdm to run, give me a GUI login prompt, but once I get into the desktop, the widgets & everything, nothing shows up, dolphin starts, but that's it.
[08:16] <hateball> any errors in journalctl ?
[08:17] <hateball> if you have /home on its own partition then a reinstall is easy enough if you do manual partitioning
[08:17] <robk> what should I look for?
[08:17] <hateball> well, errors :D
[08:18] <hateball> or in Xorg.log
[08:18] <hateball> but I guess Xorg does start
[08:18] <robk> I ran.. journalctl | grep error | grep -i xorg
[08:18] <robk> nothing shows up
[08:19] <robk> this is quiet frustrating :(
[08:20] <hateball> sorry it is quite hard to troubleshoot this stuff remotely
[08:21] <hateball> so if you pick sddm as login manager, it doesnt even load?
[08:21] <robk> I've got another HD on tis system, I'm going to copy over my /home into my ssd, and reformat this system. Lesson Learned, no longer going to ever try to install nvidia drivers on a machine until I know other people have tested this process, because nvidia can die in a fire.
[08:22] <robk> yeah, sddm just shows up a '_' in the upper left-corner
[08:22] <robk> so I installed xdm thinking somelthing might be messed up.
[08:25] <robk> yeah, this is for sure the last time I try to do anything fancy with linux desktop. It looks beautiful.. but man.. feels so sketchy
[08:26] <robk> I've used linux for years, and never had it wipe out so badly..
[08:32] <hateball> robk: fwiw I've never had problems with the PPA
[08:32] <hateball> avoid manual installs like the plague, for reasons similar
[08:32] <robk> hateball: yeah.. I'm frustrated as hell right now :(
[08:33] <hateball> it being an optimus system sadly only makes it worse as well
[08:33] <robk> I just inserted a usb thumbdrive into the laptop, going to make sure I have multi-partition setup once I copy over my 50gb of data off it, good thing for nvme/ssd on same system, evo 950 512gb nvme + 2tb evo 850
[08:33] <hateball> apparently nvidia are working on that tho
[08:33] <robk> hateball: yeah, they can work on that while I make sure in the future I avoid them like the plague.
[08:34] <hateball> :D
[08:35] <robk> getting a good 200mb/sec read/write though, which is pretty decent :)
[08:36] <hateball> nice
[08:38] <robk> how much space you think I should setup?
[08:38] <robk> for each partition?
[08:38] <robk> for kubuntu, give it like 100gb for root, and dedicate the rest to /home/?
[08:39] <hateball> all depends on your use case obvs
[08:39] <robk> ugh..
[08:39] <robk> so I use docker.
[08:39] <hateball> use 'du' before you format and find out how much you use now
[08:40] <hateball> it's not like resizing is particularly hard or time consuming on SSD either
[08:40] <hateball> one can always adjust later
[08:40] <robk> oh, so you think that I should basically just re-size the partition right now?
[08:41] <robk> that actually makes a lot of sence
[08:41] <robk> because the /home/ will be faster copying to itself than to another ssd
[08:42] <hateball> yeah you can just liveboot and resize and create new partition and move over
[08:42] <robk> I'm live-booted right now.
[08:47] <robk> my guess is all my KDE stuff is fine, my /home/<user> is fine, it's the darn drivers etc that are F'd.
[09:04] <robk> resized my partition, I'm now rsyncing my root /home to partition /home
[09:04] <robk> then going to re-install ubuntu.
[09:04] <hateball> :)
[09:04] <hateball> luckily it doesnt take so long
[09:04] <robk> hateball: that sound like a plan?
[09:05] <hateball> unless you have a million packages to install afterwards
[09:05] <robk> meh.. the data is more important.
[09:05] <hateball> robk: yea sounds good, just dont forget to do manual partitioning and dont format your /home :p
[09:05] <robk> my slack, discord, chrome, etc takes a long time just to get all the profiles setup / working etc, all the MFA stuff etc.
[09:05] <robk> yeah.. I'm going to watch that like a hawk.
[09:05] <hateball> you dont have chrome profile synced to your account?
[09:06] <hateball> google account that is
[09:32] <jubo2> Hello and thanks for the awesome desktop OS
[09:34] <jubo2> I've tried to stop the touchpad from doing unwanted things when typing with the laptop's internela keyboard (which causes unwanted touchpad action). I've done so by 'System Settings -> Input Devices -> Touchpad -> Enable/Disable Touchpad' and ticking the "Disable touchpad when typing"-checkbox and setting "Timeout" to 350ms" but these settings do not seem to be applied at all
[09:40] <jubo2> I'll ask in #kde.. maybe they know about this
[09:41] <robk> question.
[09:41] <robk> so if I backup this folder, /home/ into my new home partition.
[09:42] <robk> when ubuntu asks me to make a new user, can I cal it the same as the old one and it will resume using the same folder I had previously?
[10:13] <luxifer> Hi there... I'm on 18.04 and I find myself switching to the vterm when pressing alt+f2... is this a bug? in the past, one needed to press ctrl+alt+f2, which is the behavior I'd like to get back
[10:41] <proctrap> hey guys, I've got a problem with the taskbar going inside the clock etc: https://ibb.co/dfHASe
[10:42] <proctrap> could be related to applications getting different sized tasks: https://ibb.co/fA8Ofz
[10:49] <proctrap> option "Always arrange tasks in columns of as many rows" is the culprit
[10:49] <proctrap> without everything works fine
[10:49] <proctrap> guess I've to live with that
[11:08] <BluesKaj> Hi folks
[11:30] <hateball> robk: yes, use the same username
[11:30] <hateball> robk: and it will also get the same uid (1000) so everything should be owned by you
[11:30] <hateball> oops, 2 hours ago, maybe it is too late now
[11:31] <hateball> jubo2: is this on 18.04 ?
[11:31] <jubo2> hateball: yes
[11:32] <hateball> I think there were some changes, switch to libinput from evdev or so? iirc some devices work better or worse with one or the other
[11:32] <hateball> this is just from the back of my head tho
